A.Ymplication led August 28, 1917. Serial No. 188,661.

To all whom it 'may cerniera:

Pm. it known that l, .lesse C. Simmons, a citizen of the United States,residing at Big Rapids, county of Mecosta, State of Michigan, haveinvented certain new and useful .Improvements in TractorGearing, of

` which the following is a specification.

VThis invention relates to unprovements `in tractor gearing.

' .`he main objects of this invention are:

First. to provide an improved combined tractor gearing and belt pulleydriving device.

Second, to provide in a combined tractor caring and bclt pulley drivingdevice an improved driving gear.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a detail plan View of a struc ture embodying the features ofmy invention, the engine and various other parts being omitted.

Fig. II is a detail vertical longitudinal section on a line ceArresliionding to line 2-2 of Fig. I.

Fig. IH is an enlar ed horizontal section on a line correspoming to line?f3 of Fig. II.

Fig. IV is a detail suction on a line correspondin to line 14T-4 ofFigs. I and III.

Fig. is a detail view, partially in sec tion, on a line corresponding toline 5-5 of Fig. II.

Fig. Vl is a detail vertical section on a line corresponding to line6-46 of Fig. H1, showing details of the shifting means.

Fi VII is a detail section on a line correln the drawing similarreference characters refer to similar parts throughout the severalviews, and the sectional views are taken looking in the direction of thelittle arrows at the ends of the section lilies.

Referring to the drawin 1, 1, represent the sides or lon itudinal sil sof the running gear frame. he traction wheels 2 are mounted on the axle3. The engine is not shown, but l'. preferably employ an internalrcombustion engine.

The variable speed and reversing gearing 4; is of the shifting gcarlype,but, its dcztails form no part of my present invention l do notillustrate the same herein.

The driven shaft 5 of the transmission l herein designate forconvenience the power shaft, it being the means through which the poweris c clivered from the transmission to the pulley shaft and tractionwheels. The shaft 5 is provided with an extension (5 conn neeted theretobyi the joint 7 which permits a limited lateral movement of theextension, thus avoiding strains due to racking of the frame.. Theextension 6 extends into the gear box 8. '[he propeller shaft 9 isprovided with a worm 10 coacting with the 'worxn gear 11 of thedifferential, illustrated more or less conventionally.

.The worin 10 is provided with a housing 1&2 projecting from the gearbox S. The proi- Vcller shaft is arranged through the gear )ox andparallel with the shaft 5. The propeller shaft is provided with a gear14,'wl1ile the porter shaft extension has a gear l5 splined thereto tobe shifted into and out of mesh with the gear 14. This gear l5 is alsoadapted to mosh with the gear 16 on the stub shaft 17.

The pulley shaft la is arranged through a housing lll in bearing ".20provided therefor on the gear box. This shaft i8 is provided with a`pulley 21. The gear 16 also has a gear 22 connected thereto meshing withthe gear :'23 on the shaft 18. so that by shift ing the gear 15 intomesh with the gear 14, the propeller is driven; by shifting it into meshwith the gear lll the pulley shaft is driven.

By arranging the is connected with pulley shaft so that it the source ofpower through the variable speed gearing` the pulley shaft may be driventhrough the desired transmission speed which enables picking up orstarting .of a very heavy load on the pulley shaft. It is Wellunderstood that an engine is capable of driving certain loads which itis unable to start or to overcome the inertia.

B v arranging the driving connections as I hate illustrated anddescribed the load may be picked up on low gear and various gear shiftsmade as may be desirable.

In the structure illustrated the shlftable gear 15 is adjusted from theshifting rod 24 which is arranged through the rear side of the gear boxand provided with a suitable hand picce. This rod carries the forked arm25 which engages thc groove 26 of the gear 15, so that the gear 15 maybe easily shifted as desired.

I have illustrated and described my im provements in the form in which Ihave embodied the same irr practice. I have not attempted to illustrateor describe certain modifications and adaptations which I contemplate orwhich might be desirable to adapt my im rovements to various conditions,as I be ieve the disclosure made will enable those skilled in the art towhich my invention relates to embody or adapt the same as may bedesired.

Having thus describe my in vcntion, what I claim as new Vand desire toseeure by Letters Patent, is:

l. The combination of a variable speed gearing comprising a pdvvershaft, a gear box, said power shaft being provided with an extensionhaving a connection therewith permitting relative lateral movement dis--posed in said gear box, a driven shaft disposed through said gear boxbelow said power shaft, a gear on said driven shaft, a pulley shaftdisposed through said gear box above and transversely of said powershaft, a beveled gear on said pulley shaft, a pulley shaft driving gearhaving a heveled gear connected thereto and meshing with said pulleyshaft gear, and a shiftahle power gear splined upon said power shaft.extension to be shifted into engagement with said driven shaft gear orwith said pulley shaft driving gear.

2. Ihe eombinationi of a variable speed gearing comprising a powershaft, a gear box, said power shaft being extended into said gear box, adriven shaft disposed through said gear box below said power shaft, agea r on said driven shaft, a pulley shaft disposed through said gearbox above and transversely of said power shaft, a beveled Year on saidpulley shaft, a pulley shaft rriving gear having a beveled gearconnected thereto and meshing with said pulley .shaft gear, and ashiftable power gear splined upon said power shaft to be shifted intoengagement with said driven shaft gear or with said pulley shaft drivinggear.

3, In a tractor-,thecombination ofapower shaft, a gear box, said powershaft being provided with an extension having a connection therewithpermitting relative lateral movement. disposed in said gear box,V adriven shaft disposed through said gear box below said power shaft, agear on said driven shaft, a ulley shaft disposed through said gear boxa 0" and transversely of said power shaft, a beveled ur on said pulleyshaft, a pulley shaft driving gear having a beveled ear connectedthereto and meshing with said pulley shaft gear, and a shiftable power'gear splined upon said power shaft extension to be shifted intoengagement with said driven shaft gealpor with said pulley shaft drivinggear.
